What can you measure?
Surface finish on functional surfaces
Inspect accessible bearing seats, sealing surfaces and other machined features. Select stylus geometry, traverse direction and measurement length for the feature.
Roughness inside bores and recesses
Measure internal or recessed surfaces with a suitable probe and drive arrangement. Check stylus clearance, reachable depth and the available traverse length.

What to consider before choosing
Surface requirement
Provide the required parameters, drawing standard, cutoff or filtering requirements and evaluation length.
Tracing access
Describe the surface curvature, available travel and whether transverse tracing is needed.
Measurement system
Select skidded or skidless measurement with the appropriate probe, fixture, reference and reporting software.
Frequently asked questions
Which roughness tester should I choose for shop-floor inspection?
Start with the drawing’s roughness parameters, available tracing length and surface access. Compare the portable PS 10 and M 310 configurations with the other listed systems according to the measurement method and reporting needed.
When should I consider a skidless system instead of a skidded tester?
The choice depends on the surface characteristics and evaluation required. The India list separates skidded PS 10/M 310 options from skidless M 410 options. Supply the drawing requirements so the reference method, probe and evaluation can be checked together.
Can the instrument measure inside a bore or across a narrow feature?
It depends on probe access, tracing direction and the space available for the measurement. Provide the bore size or feature width, depth and required trace location. A standard pickup should not be assumed to fit every feature.
